MKPinAnnotationView doesn't set custom image

I have to set custom image for different pins. With my code I'm able to set custom color for each of them but when I try to set custom image instead of colors, it doesn't work.

- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(MyAnnotation *)annotation {

static NSString *identifier = @"MyLocation";

if ([annotation isKindOfClass:[MyAnnotation class]]) {

    MKPinAnnotationView *annotationView = (MKPinAnnotationView *)[self.myMap dequeueReusableAnnotationViewWithIdentifier:identifier];

    if (annotationView == nil) {

        annotationView = [[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier];

    } else {

        annotationView.annotation = annotation;

    }

    annotationView.enabled = YES;
    annotationView.canShowCallout = NO;

    NSString *stringType = [NSString stringWithFormat:@"%@", [(MyAnnotation *)annotationView.annotation stringType]];

    if ([stringType isEqualToString:@"0"]) {

        annotationView.image = [UIImage imageNamed:@"IconUserCerco.png"];
        //annotationView.pinColor = MKPinAnnotationColorGreen;

    } else if ([stringType isEqualToString:@"1"]) {

        annotationView.image = [UIImage imageNamed:@"IconUserDefault.png"];
        //annotationView.pinColor = MKPinAnnotationColorPurple;

    } else if ([stringType isEqualToString:@"2"]) {

        annotationView.image = [UIImage imageNamed:@"PinUniversity.png"];
        //annotationView.pinColor = MKPinAnnotationColorRed;

    }

    return annotationView;

}

return nil;

}

Any help will be much appreciated. Thanks in advance.

This is what it looks like in iOS 11.x Swift 4, note this won't work if you make the same mistake as me using MKPinAnnotationView. This will make a pin and you won't be able to change the image behind it.

func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {

    if annotation is MKUserLocation  {
        return nil
    }

    let reuseId = "pin"
    var pav:MKAnnotationView?
    if (pav == nil)
    {
        pav = MKAnnotationView(annotation: annotation, reuseIdentifier: reuseId)
        pav?.isDraggable = true
        pav?.canShowCallout = true
        pav?.image = UIImage(named: "WIP.png")
        pav?.calloutOffset = CGPoint(x: -8, y: 0)
        pav?.autoresizesSubviews = true
//      pav?.rightCalloutAccessoryView = UIButton(type: .roundedRect)
        pav?.leftCalloutAccessoryView = UIButton(type: .contactAdd)
    }
    else
    {
        pav?.annotation = annotation;
    }

    return pav;
}

Instead of MKPinAnnotationView can you use MKAnnotationView? You'll have to use following instead of MKPinAnnotationView

MKAnnotationView *annotationView = [self.myMap dequeueReusableAnnotationViewWithIdentifier:identifier];

iOS 9.0 onwards its recommended to use MKAnnotationView. That should solve your problem.
